IMPROVEMENT IN CORRU'GATED REFLETORS.

The Schedule referred to in these Letters P atent vand makng parl: of the same.

To all whom'tt may concern:

,Be it known that I, BERNARD Gqnrz, of the city of Ihilzulelphia, county of Philadelphia, and State of Pennsylvania, have invented a new4 and` useful Im- -provernrent in Corrugated Iteectors; and I do here# 'by declare that the following is a full, clear, and exact side toward each other, and intersected from the back ofthe plate by parallelgrooves, and crossed by other series of grooves, all tending toward a common centre or focus. I j

In the present improvement, the' rays of the light are not drawn to a common centre or focus, but are broken and diffused more thoroughly throughout the room,4 by corrngatiug the plate in the form of squares or diamonds, as will be hereinafter described.

Figure 1 is a plan view of my improvement in corrugated reflectors.

Figure 2 is an edge View of same, with a portion of the framing removed. f g

'lo enable others skilled=in` the art to make and use my invention, I will now proceed to describe its construction and operation.

. Plate Ais made of composition', or any metal suitable for the purpose, and is coated with silver, so asl to make it durable and susceptible of a high polish.

The said plate has formed on its surface, by means of diagonal. lines .,li,i.c, d, e, f, g,'&c., iutersected by the diagonals a', b', c', d, e', j", g', 85C-2, a series of squares ,or diamonds.`

.'lhese diag'onals are made on the back ofthe plate, so'as to raise the sides -of the squares or diamonds on the surface. l

Also, on the surface of the plate is formed a series of parallel grooves' or fnrrows h, h1, h2, and it, so as to give it a wavy appearance, and better diluse the light.

. Plate A, thus prepared, is set iu a frame, F, of any desired form, and the plate protected from the weather bymeans of a glass plate, GP, as shown in iig'. 2.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is

'.Lhe plate A, having on its surface a series of squares formed by diagonal lines c, b, c, d, e, f, g, Sto., intersecting diagonal lines a', b', c', c" e', f', g', 85o., and also having a sei-ies of parallel grooves or furrows, h, h1, h2, and h, substautiallyias and for the purpose set forth.'

. In testimony whereof, I have hereunto signed my name, in the presence of two subscribing witnesses.

Witnesses: BERNARD GOETZ.
